To all whom it may concern i Be it known that I, EDOUARD FaANgoIsDELAMARE DEBOUTTEVILLE, a citizen of the Republic of France, apdaresident of'Rouen, Seine Infrieure, France, havejnvented a cerlainImproved Machine for Shaping, Drilling, I Boring, and Facing Metals,(for which French Letters ,Patent No. 142,510, April 25, 1881, andBritish Letters Patent No. 1,910, May 3, 1881, have been granted,) ofwhich the following is a specification.

My invention relates to certain improvements in the construction ofmetal-working machines; and it consist in so constructing the machinethat the article to be operated on, when once placed in position, may bedrilled, bored, slotted, milled, planed, surfaced, and

' otherwisefinished without being removed from the work-table. By thismeans the work will be executed with greaterprecision and in much lesstime than in the ordinary waywith aseparate machine for each operation.Atthe same time the machine is so constructed as to insure a firmrigidityot' the parts, and thereby obtain perfect regularity in the workdone.

In the accompanying drawings, Figure 1, Sheet 1, represents aside viewofmy machine; Fig. 2, Sheet 3, a rear elevation Fig. 3, Sheet 2, asectional plan on the line 3 4, Fig 4; Fig.

0 4, Sheet 2, a vertical section on the line 1 2, Fig. 3; Fig.5,Sheet4,a frontelevation, partly in section; Figs. 6 and 7, Sheet 3,enlarged sectional views of a part of the operating devices of themachine; and Figs. 5,8, and 9,

3 "detached views of parts of the apparatus.

A is a horizontal bench'bolted to the baseplate B, which is cast in onepiece with a standard, B. The upper part of this stand ard is curvedover and terminates in two ex- 0 tensions, a, which serve as guides to avertical slide, G.

To guides on the horizontal bench A is adapted a saddle or carriage, O,to which a longitudinal motion on the bench may be imparted, ashereinafter described; and this saddle O is provided with guides atright angles to those of the bench A, and on these guides is mounted asecond carriage, D, to which a 'transversemotion may be imparted. Onthis second carriage D is mounted a table,p, which is adapted to berotated in a horizontal plane by the devices hereinafter described, andon which the work to be done is placed and secured.

The lower end of the slide 0 carries a tool- 5 holder, 0, which maybe ofthe ordinary construction. The slide also carries a vertical spindle, g,to which the drilling and similar tools are secured, and to which arotary motion maybe imparted,as hereinafterdescribed. 6o Washers 0 0 areprovided to compensate for the wear on the shoulders or collars on thespindle g, bearing against the bearings in the slide 0.

The principal portion of the driving-gear is arranged in the rear of thestandard B, and the machine may be driven by a belt passing over acone-pulley, P, the shaft of which carries a bevel-wheel, r, and pinionp, for transmitting power to different parts of the-ma- 7o chines. Thusthe rotary motion of the pinion 1) is transmitted (Fig. 4) through thegearwheels of, bevel-Wheels h It, and gears t and j to the tool-spindley when the wheel f is made fast to its shaft by the screw d. The upperend of the spindle 9 passes through the wheel 9', and is provided with afeather, so thatwhile it can slidefreely through the wheel in partakingof the vertical motion of the slide 0, Fig. 4, the tool-spindlerotateswhen the wheelj is rotated.

The miter-wheel 'l transmits motion, when desired, through thebevel-wheels It, l, and M, Fig. 4, to the carriages'O D and table 1),carrying the work.

The main shaft, carrying the driving-pulley P, also carries a pulley,pFigs. 3 and 4,which, through the intermediate belt-pulleys, 1" r Figs.1, 2, 3, and 5, drives the pulley E for operating the differentialmovement on the shaft 0 G, Fig. 1, as more fully described hereinafter.

Having now briefly referred to some of the principal operating parts ofthe machine, I will proceed. to describe in detail the separate parts:first, the bench,sliding carriages,worktable, and accessories; secondly,the tool-carrying slide and its parts; and, thirdly, the difi'erentadjustments and. operations of the machine for the various classes ofwork to be done. IOO

I. The 'ZCOTL-MMG.AS indicated above, the work-table may have threedifferent motions imparted to it in a horizontal plane: first, alongitudinal motion by the movement of the carriage G on the bed;second, a transverse motion by the movement of the carriage D on thecarriage G; and, third, a rotary motion of the table on the carriage D.The longitudinal motion of the carriages and table on thebench may beeither slow or fast, according to the nature of the work (milling orplaning) to be done. The slow longitudinal motion is imparted to thecarriages by means of a screwshaft, V, mounted in bearings in the benchA, and carrying atits outer end a band-pulley,g, which is loose on theend of the screw-shaft, but may be fixed thereto by screwing up thetightening-nut r,whichjams thepulleyagainst a shoulder on thescrew-shaft V, as shown in Fig.1. Thisconvenientconstructionofcouplinghas the advantage ofrendering the dismounting of any of the parts tostop the motion unnecessary, and permitsarapid change from mechanical tohand power when necessary, the end of the screw-shaft being providedwith a crank-handle for the purpose. This coupling possesses the furtheradvantage of permitting the automatic stoppage of the movement of thescrew Vshould any unusual obstruction be presented to the tool,for thenthe frictional clamping action of the wheel a will not be sufficient toprevent the pulley g from slipping on the shaft V. The shaftV passesbetween the two parts of a nut, (l (I, Fig. 5, which is guided in lugsprojecting from the under side of the carriage C. The two parts of thisnut may be brought together and into gear with the screwshaft, orseparated and out of gear therewith, by means of a disk, 1:, Fig. 5provided with cams or eccentric slots and operated by means of asuitable handle, at, Fig. A band from the pulley 9 passes over a pulley,0n the end of the horizontal shaft G, Fig. 3, to which a rotary motionis imparted by the ratchet-wheel 7." or differential motion operated bythe pulley E, as hereinafter described, so that when the pulley g issecured to the end of the screw-shaft and the two-part nut (I put intogear with the screw-shaft V a rotary motion will be imparted to thelatter, and consequently a longitudinal movement to the carriage andwork-table. When it is desired to imparta more rapid longitudinalreciprocating motion to the carriages and table, the two-part nut (I isseparated out of gear with the screw-shaft and the pulley 9 set freethereon, and an adjustable connecting-rod, H, pivoted to the carriage Cat a, Fig. 4, is attached to a crank-pin secured to the face of thedriving-wheel M, this crank-pin being ad-.

justable in radial guides in the latter to the proper position forgiving the desired extent of travel of the carriages and the work on thebench. The desired transverse motion of the carriage D on the carriage Cis obtained through the medium ofa screw-shaft, 1', Figs.

3, 4, and 5, which is adapted to bearings b" in the carriage C, andpasses through a threaded socket secured to the under side of thecarriage D. Rotary motion may be imparted to the screw-shaft 21 from theshaft Gr through the medium of the bevel-wheels l 021, Fig. 5, pinion n,and gears 0' 1), Figs. 1 and The bevel-wheel I is connected to the shaftG by a groove and feather, so that while it turns with the shaft it canslide thereon longitudinally. To the under side of the table 12 issecured a worm-wheel, 00 into which gears a worm, :0 Figs. 1 and 5,keyed on a transverse shaft, 1, adapted to bearin gs in bracketsprojecting from opposite sides of the carriage C. 0n the end of thisshaft t is a pinion, (1, which gears into and is driven by the pinion 0before referred to. Each of the pinions p and q is normally loose on itsshaft, but can be clamped thereto by a screw-clamp similar to that o forthe pulley g, and each shaft 'tand t is provided with a crank, by whichit may be turned by hand. At the opposite end of the shaft t from thepinion q is a dividing-plate, Q, hereinafter referred to, and thebearing .for the said shaft 1:, adjacent to this dividing-plate, isprovided with abindingscrew, 1?, Fig.8, by which the shaft may besecured in any position and prevented from turning while the machine isbeing used for planing, drilling, &c. The opposite bracket-bearing forthe shaft t is adjustably secured to the carriage 0, so as to allow forcompensation for wear of the worm-wheel and worm. The dividing'plate Q,which, as shown in Figs.8 and 9, is mounted on a sleeve secured to thebracketbearing, has, say, one thousand divisions marked on it. It isprovided with an annular undercut or T-shaped recess, to which areadapted buttons orstopsmm. Thetirstbutton, m, always remains fixed atzero, while the other, m is adjusted away therefrom, according to thenumber of divisions it is intended to mark on the work. A handle orpointer, M, to move between these two points, can be made fast or looseon the shaftt by means of a gripping collar and cam, 0 to provide forturning the table 1) through the screw 00 the extent of one division atatime. The differential movement, by means of which the shaft G may berun fast or slow or left loose, is shown in detail in Figs. 6 and 7. Apulley, E, mounted loosely on the shaft G and driven by belts from thepulleys r r, is provided with a fixed radial axle, on which is mounted abevel-wheel, c. This bevel-wheel, which may be allowed to run free onits axis or be fixed thereto by a set-screw, .7, gears on one side intoa bevel-wheel, n, keyed to the shaft G, and on the other with abevel-wheel, c, mounted loosely on a fixed sleeve, in which the shaft Gturns. The bevel-wheel 0 may be made fast to its sleeve by means of afriction screw-couplingw, similar to those above referred to. To run theshaft G at a moderately slow speed, the wheel 6 is secured to its ICQbolt or catch, z", as shown in Fig. 5.

fixed axle by the set-screw z, and thecoupling c loosened, so thatthe'pinion a, which is keyed to the shaft G, will turn at the same speedas -the pulley E. To increase the speed the screw 2 is loosened and thecoupling a screwed up, so that the pinion n and shaft G will run attwice the speed of the'pulley. By loosening pawl k of this ratchet k iscarried by one end of a pivoted lever, is, Fig. 7, the opposite end ofwhich is connected by the link k to an cecentric, f, on the shaft F ofthe wheel M. The table 12, carrying the work, can thus be moved in alldirections horizontally below the tools at different speeds, and eitherby mechanical or hand power, according to the requirements of the workto be done.

II. The tool-carrying sZide.--The tool-carrying slide 0 canhaveaverticalmotion imparted to it on guides on the standard, and thismotion may be either simply for adjustment or slow or rapidlyreciprocating, according to the work to be done. The cutting-tool, sayfor planing, is fixed in the block b on the toolholder 0, carried by thelower end of the slide, and constructed in the usual manner, so as totip or yield on the return-stroke. The toolholder 0 is provided with atoothed sector and worm b, by which any desired inclination may be givento the holder 0. At the back of the slide is a helicoidal rack, H, Figs.3 and 4, into which gears the worm h mounted in bearings in the lever L.This lever is pivoted at its outer end to the standard B, and may bemoved by hand, so as to throw the worm k into or out of gear with therack, as required, and itis held in either position indicated by dottedlines in Fig. 3 by means of a sliding 0n the lower end of the axis ofthis worm is a pinion or ratchet-wheel, into which takes a pawl on asecond pivoted lever, L, below the lever -L. By the horizontal vibratingmotion of this lever L on its pivot the ratchet is intermittentlyrotated, and through it the worm k is rotated, and the latter, acting onthe rack H, causes the slide 0 to rise or descend, as may be required.This horizontal vibrating motion may be imparted to the lever L tooperate the slide either by hand or mechanically. In the latter case thelever L is connected by rods 1 Z and lever Z to an eccentric on the axleF of the wheel M. When it is desired to give a rapid verticalreciprocating motion to the slide 0, as for slotting, the slide isconnected by the rod P with the crank-disk P which is mounted on thesame shaft as the gear-wheel 6, Fig. 4. The length of stroke orextentot' movement of the slide can be regulated by adjustingthecrank-pin in a radial slot in the disk P. The vertical spindle g, which,as before described,

is mounted in hearings in the slide 0, and can be rotated from thepinion p by the gearing e, f, h, h, a, and j, is adapted to receive asuitable metal-working tool, such as a boring-bit or a millingtool.rotary cutting'tool, s, for cutting wheels or dividing, is provided,this tool being carried by a support, S, Figs. 3 and 4, to which an upand-down motion on slides can be given by a suitable pivoted lever.drawings.) Thesupportmaybesoconstructed and adapted toits slides that aslight inclination may be given to it when desired. The rotarycutting-tool is driven by a belt or band from some moving part of themachine, as indicated by dotted lines in Figs. 3 and 4 for instance.

III. Operations.'1he different adjustments of the various parts forcarrying out the different operations of which the machine is capablewill now be briefly described.

For planing-The carriage O is connected to the crank-pin on the rotatingwheel M by the connecting-rod H, so as to impart a rapid horizontalto-and-fro motion to the carriages, work-table, and work beneath thecutting-tool in the holder 0, the slide 0 having been adjusted to theproper height. The necessary transverse intermittent feed motion of thework after each cutis etlected by the action of.

the screw-shalt e on the. carriage D, this screwshaft receiving itsmotion from the shaftGr through the gearing above described, and theshaft G being acted on by the pawl k and ratchet it, while all the othermovements are thrown out of gear. The cutting-tool is fixed in the blockb by screws, and a small spiral spring, Fig. 4, is employed to bring thetool to its cutting position after each stroke.

Turning and boring-The pinion qis clutched to its shaft tand thedifferential movement so adjusted that the pinion n and shaft G run atthe same speed as the pulley, and the shaft G transmits rotary motion tothe shaft 25, and thence by the worm m to the table 11 on the carriageD. The turning or boring tool is fixed in the holder 0, and the slide 0is caused to descend slowly by the action of the lever L and its pawl(operated by hand or automatically) on the ratchet of the worm 7L whichgears'into the rack on the back of the slide. The other movements,during this operation,

'are of course thrown outof gear.

Drilling-The carriages G and D and table 12 are fixed withthe work inposition under the spindle g. The gear-wheelf, which at other times isallowed to run loose on its shaft, is now fixed thereto by its screw d,so that a rapid rotary motion through the gearing above described isimparted to the spindle g, to which the drilling-tool is secured. Therequisite downward pressure of the spindle and tool is obtained bycausing the pawl-lever L to depress the slide C, as before described.

Slotting.-F0r this purpose the slotting-tool is fixed in the holder 0 bythe usual screws,

To complete the machine a- (Not shown in the LII 1 275,60&

and the tipping motion of the block, which is used in planing, preventedby means of the screw 10, Fig. 4. The slide 0 is connected to thecrankpin on the rotating disk P through the medium of the connecting-rodP, so as to impart a vertical reciprocating motion to the slide andtool. The necessary feed motion between the strokes of the tool isimparted to the work by putting the screw V in intermittent action, soas to move the carriages and work-table longitudinally on the bench A,or by putting the screw 1; into action to move the carriage I) andwork-table transversely, according to the requirements of the slot to becut.

Sm '/hcing.'lhe surfacing-tool istixed in the lower end of the spindleg, to which a rotary motion is imparted by the means above described,and the slide 0 may be caused to descend slowly, or may he held at anydesired height. The work-table may be moved in any directionhorizontally by the devices before described, according to the form ofthe work to be surfaced.

Dividing or whc0I-cutting.-The rotary cutting-tool is fixed to thecarrier 8 of the adjustable support S and motion communicated to thetool by belts,and the table is adjusted to a position within range ofthe tool, and after each cut is moved or adjusted for the next cut bymeans of the handle M, Figs. 5, 8, and 9, of the divider Q, which handlehas been clamped to the end of the shaft t for the purpose.

The foregoing are the principal operations which can be effected on thismachine, whereby the most complicated pieces of work may be finishedwithout being removed from the machine.

I claim as my invention- 1.
